I would not be a bit surprised to learn that camper shell was presented as a 1:1 concept to an aftermarket manufacturer.
It would be a heavy sucker in fiberglass, but it shows some very smart thinking.
AMT had a side hustle looking for projects through their 'Speed and Custom' business responsible for what became Pirhana, and a package of scoops and spoilers for Camaro and Firebird.
Regardless, a cool item that might be interesting on some other pickup kits, like a dentside F-series.
